What is more processing power - 10x, $5 vps or 1, $50 dedi
I would say the 10x $5 ones would be the clear winner.
Why? Here is my case:
I have an 8core amd 8320 as my home machine, certainly not a top of the line processor but not too shabby. I run that on my encoding script and it will take around 12 hours to complete. This is the same as being a 'dedi' since I am the only one using it.
On the other hand, 1 $5 vps will take around 2-3 days to complete the same script. As such 10 x 2-3 days = way more than just 1 dedi because I doubt anything would beat that for 50 bucks a month. A dedi would need to be at least 10 times faster to be worth buying but for 50 I don't think you could get any server to do that.
